Hi all, I've had for a long time ispconfig installed only for hosting websites not emails, i've decided to configure an account and test it out, although my mailbox fills in with recurring error mails that contain the following: And i don't even do nothing, i just configure that mail account on Outlook and do a Send and Receive and tons of those messages come, and i have to stop the service to make them stop. Also i can configure the account on Outlook and do a test message without having the "my server (smtp) requires autentication", how can i change that? Thank you for your help.
Please add localhost.localdomain.xxxxxx.com at the end of /etc/postfix/local-host-names and restart Postfix.
